We are presently running Windows SBS 2011.  We are port forwaring 443 from an external IP, which we are performing 1to1 NAT, to the server on an internal IP.  Up until today it has worked great.

Today, we installed all the windows critical updates and we installed AVG anti-virus.

We are able to, from the LAN, browse to https://remote.domain.com and get the web login screen.  When we login from the Internet, we are getting the error from IE, The page you are looking for could not be found.

We checked DNS, it is resolving correctly.
We checked the port forward, it is working fine on 443 and 3389 for RDP.  RDP is working great.
We have gone to the application events and we do not see denials.

Thoughts?

Thank you ahead of time for your feedback!

TCP 987 was opened with no affect.

I rebooted Windows SBS 2011 and the service was restored. Not sure what was happening as of yet, but it is working now.  Thank you for your input.

After confirming with the firewall that all ports hadn't changed, and adding the additional TCP port 987, I have determined that it wasn't the firewall.

I rebooted the server and service was restored for outside remote.domain.com access.  Not sure what happened at this point. Waiting for the situation to duplicate in order to see if it happens again to specifically diagnose.
